Patent DE-19641059-A1 (DE)
Title: Continuously variable transmission for motor vehicle
Inventor: TOUKURA NOBUSUKE
IPC: F16H61/16
Filed: 1996-10-04
Abstract: The continuously variable transmission (CVT) sets the transmission ratio to a programmed control in response to the throttle setting, engine speed, vehicle speed etc. For engine braking, when running down an incline with the throttle pedal released, the control applies a variable correction factor by altering the transmission ratio and thereby providing a controlled amount of engine braking. The control detects if the throttle has been released and provides a corresponding command signal to the engine braking control system. The vehicle acceleration is monitored and kept below a threshold value by changing the transmission ratio of the CVT.

Title: Marking insert for a plastics injection or compression moulding tool
Inventor: SCHROEDER HARALD
IPC: B29C45/37
Filed: 1997-01-15
Abstract: A marking insert (10), especially for plastics injection or compression moulding tools, has a rotatable insert (12) with date markings at the front and a rear  face (14) supported on a shoulder (25) of a collar (28) in a housing (11). A peg (15) extending from the rear face (14) passes through a compression spring (33) between a shoulder surface (30) on the rear of the collar (28) and a supporting body (35). A system to prevent unwanted rotation of the date insert (12) comprises a locking arrangement (K) on peg (15) which when the insert (12) is rotated engages with a locking system (S) on the supporting body (35) and presses the latter axially against the rear (32) of the spring (33) to maintain the set position. The supporting body locking arrangement (S) comprises at least one circular cylindrical pin (40,47) projecting radially inwards from the supporting body (35) towards the peg (15) and the peg locking arrangement (K) includes an annular groove (19) at a distance from the peg end face (17) and a lead-in groove (18) for the engaging pin (40) which enters the annular groove. Side walls (21,22) of the grooves (18,19) form rolling surfaces (23) for the pin (40). Preferably the supporting body (35) is an annular disc located in a circular cylindrical bore (43) in the housing (11). A radial hole (46) in the supporting body (35) has an elongated cross-section running parallel to the insert axis (R) allowing axial movement of the body relative to a radial cylindrical pin (47) with a diameter equal to the width of the elongated hole. The lead in groove (18) runs axially into the annular groove (19) and the rolling surfaces (23) have a convex curvature to lift the pin (40) and supporting body (35) against the spring (33) as the insert (12) rotates. An ejector spring (57) and disc spring (59) press axially against the rear end face (17) of the peg (15) forcing the engaged pin (40) and supporting body (35) against the compression spring (33) which exerts a higher force than the ejector spring.

Patent DE-19737839-A1 (DE)
IPC: B65G49/07
Filed: 1997-08-29
Abstract: The invention relates to a transport system for conveying products during the production process, especially integrated semiconductor products, to facilities inside a building, where they are submitted to factory processing.

Such a system is advantageously built separately from the machining center, resulting in a significant increase of the supply pace. It enables any place in the plane of the system to be reached and to be accessed any time in case of failure. It also provides with the possibility to significantly reduce the complexity of the driving software.
Patent DE-19748764-A1 (DE)
Inventor: WICHELHAUS WINFRIED DR
IPC: C09D5/24
Filed: 1997-11-05
Abstract: The invention relates to conductive, weldable anti-corrosion compositions with a base consisting of (blocked) polyurethane resins, epoxide resins and nitrogenous resins and conductive fillers. The inventive compositions are suitable for coating metal surfaces, especially steel sheets, using the coil-coating technique, and are characterised by a low burning-in temperature, by a significant reduction of white rust on galvanised sheet steel in the salt spray test and in that the organic coating adheres better to the metallic substrate. These coatings also provide adequate protection against corrosion even with low chrome plating, preferably also with Cr-free pre-processing techniques. Sheets coated in this way can be spot-welded using any conventional technique.
